Looking for the best gym in the heart of Llansamlet? We’ve filled our bright and spacious gym with the best energy, equipment, technologies, and trainers around. We know you want results, and that’s what you’ll get. With a huge free weights area, tons of functional fitness spaces, state-of-the-art digital cardio machines and free group exercise classes, we’ve got everything you need. Choose Simply Gym Llansamlet today and we promise you'll never look back!

We're excited to announce that Simply Gym Llansamlet is going into a major refurbishment and will be re-opening later this summer as JD Gyms Llansamlet! We'll be improving the free weights zone, adding brand-new plate-loaded kit and cardio equipment, including brand-new treadmills. We’ll also be improving the functional training zone and adding a dedicated glute and tone area, as well as making extensive decor improvements and upgrades to the changing rooms.

PLUS... When we re-open as JD Gyms we’ll be a 24/7 gym, so you can work out around the clock, 24 hours a day!

Work will begin on Monday 22nd July. To keep disruption to your workouts to a minimum, the gym will remain open for the majority of the work. We will have a short closure period prior to our re-opening later this summer, which we will confirm nearer the time, as we hope to get as much done as possible whilst we are open.
